I have always used aspire tanks and coils since I stopped smoking cigarettes and switched to vapor for health reasons. The old dual coils worked perfectly for me. But ever since they were redesigned I have had major problems with them tasting burnt. I go through the same process when using a new coil: Letting it sit for 5 minutes to allow the juice to absorb, Hitting it without igniting the battery to get the juice in the coil, etc. But even with doing this I still get a burnt taste with at least 2 out of the 5 in a pack. This has happened not once but twice. The last 5 pack I bought 3 of them had this defect. Just to be clear the other ones worked just fine with my process so I know it's not my equipment.
I have gone back to the shop owner multiple time who I have built a friendship with and he said he has other people come in with the same problem. So at this point i have paid and lost to defectiveness an entire 5 pack of coils. I'm not sure what can be done about this minus aspire replacing some coils which would be greatly appreciated. But perhaps also looking in to the new design to see if there is a flaw in the product line. I don't want to switch to a new tank and coil because I'm loyal and like aspire so I'd like to stick with it. However I can't keep purchasing coils and having half of them not work. Any advice or help would also be greatly appreciated. Thanks for any and all help!
